The ischemic myocardium mobilizes Ly-6Chi and -6Clo monocytes in two distinct phases. Cell suspensions from healthy hearts or infarcts of C57BL/6 mice were stained with anti-CD11b, -CD90, -B220, -CD49b, -NK1.1, -Ly-6G, -Ly-6C, -F4/80, -I-Ab, and -CD11c mAbs. Monocytes/macrophages/dendritic cells were identified as CD11bhi (CD90/B220/CD49b/NK1.1/Ly-6G)lo. (A) Representative dot plots from individual mice within the monocyte/macrophage/dendritic cell gate depict Ly-6Chi monocytes (Ly-6Chi [F4/80/I-Ab/CD11c]lo), Ly-6Clo monocytes (Ly-6Clo [F4/80/I-Ab/CD11c]lo), and macrophages/dendritic cells (Ly-6Clo [F4/80/I-Ab/CD11c]hi) in healthy hearts and within the infarct at specified days after MI. Percentages of cells are shown as the mean ± the SEM. (B) Relative percentage of monocytes and macrophages/dendritic cells. (C) Relative percentage of Ly-6Chi and -6Clo monocytes. (D) Total number of neutrophils per milligram of tissue. (E) Total number of monocytes and macrophages/dendritic cells per milligram of tissue. (F) Total number of Ly-6Chi and -6Clo monocytes per mg tissue. (G) Time course of leukocyte infiltration to infarct. The mean and the SEM are shown. Results are pooled from 6 independent experiments with 3–10 mice per group.
